For example, those skilled in the art can obtain other drawings based on these drawings without paying any creative work.

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

The terms "component," "module," "system," and the like, as used in this specification, are used to mean a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer.

However, for low-latency, high-reliability transmission services, not only the transmission delay is required, but also the requirements are reliable, such as V2V (Vehicle to Vehicle) or V2X (Vehicle to Everything). If the transmission is unreliable, it will cause retransmission and the transmission delay will be too large to meet the requirements.

FIG. 2 shows a schematic flow chart of a service transmission method 200 in accordance with an embodiment of the present application. As shown in FIG. 2, the method 200 can include:

210. The terminal device determines an adjustment offset, where the adjustment offset is used to adjust a first scheduling period of the first service of the terminal device, where a period length of the second scheduling period is different from a period length of the first scheduling period.

220. The terminal device adjusts the first scheduling period according to the adjustment offset, to obtain a second scheduling period.

230. The terminal device sends data of the first service according to the second scheduling period.

In this embodiment, the peer end of the terminal device may be a network device, or may be another terminal device.

In the embodiment of the present application, at the data receiving end, the scheduling period may also be referred to as a sending period, and refers to a time interval for transmitting two adjacent data packets. If the description "sends the data packet A according to the scheduling period A", it means that the transmission time interval between the data packet A and the previous data packet is the transmission time interval corresponding to the scheduling period A.

The scheduling period of the embodiment of the present application may be referred to as a semi-persistent scheduling period or a semi-persistent scheduling period.

Optionally, in the embodiment of the present application, the network device may pre-configure an initial scheduling period of each service of the terminal device, that is, a first scheduling period. The network device may further configure the value of the adjustment offset of the scheduling period to the terminal device, where the value of the adjustment offset may be a value or a range (also referred to as an offset window), if it is a For the range, the terminal device can randomly select the adjustment offset from the range of values.

Optionally, in the embodiment of the present application, the value of the adjustment offset may be in units of time slots, or may be in units of subframes.

Optionally, in the embodiment of the present application, the terminal device may determine the used time-frequency resource before sending the data of the service by using a certain scheduling period, where the time-frequency resource is used to indicate that the frequency corresponding to the service is sent. The domain resource and the scheduling period of the service correspond to time domain resources in the subframe. For example, the terminal device determines the data of the service sent by the carrier 1 and the time slot 1, and the time domain interval corresponding to the current scheduling period is 5 subframes, and the service may be sent by the carrier 1 in the time slot 1 of the first subframe. Data, then, the carrier 1 transmits the data of the service in slot 6 of the sixth subframe, and so on.

Optionally, in the embodiment of the present application, the terminal device may determine, by the network device, the time-frequency resource indicated by the physical layer control channel as the time-frequency resource used by the terminal device to send the service data by using the corresponding scheduling period. Alternatively, the terminal device selects the time-frequency resource from the resource pool as the time-frequency resource used to send the service data by using the corresponding scheduling period. Alternatively, the terminal device may use the time domain resource used in the previous scheduling period as the time domain resource used in the current scheduling period.

Optionally, in the embodiment of the present application, the network device may first configure the value of the adjustment offset to the terminal device, but does not activate the terminal device to adjust the currently used scheduling period. The activation message is sent to the terminal device to adjust the current scheduling period, obtain another scheduling period, and send the service data according to the adjusted scheduling period. Optionally, in the embodiment of the present application, the activation message may further indicate the time-frequency resource mentioned above for performing service data transmission by using the adjusted scheduling period.

Optionally, the foregoing activation message may be physical layer signaling or Media Access Control (MAC) signaling. Therefore, in the embodiment of the present application, the network device can quickly trigger the terminal device to adjust the scheduling period by using the physical layer signaling or the MAC layer signaling, for example, the network device determines the resource conflict of the service data of the multiple terminal devices. At the same time, all or part of the terminal devices are activated to adjust the current scheduling period. Therefore, the embodiment of the present application can quickly trigger the corresponding configuration when needed to ensure the quality of service transmission.

Optionally, the network device may adjust each configuration parameter by using control signaling, for example, Radio Resource Control (RRC) signaling or MAC signaling, for example, the foregoing time domain resource, scheduling period, and offset adjustment. The value, the resource pool, and the like are sent to the terminal device, and the configuration parameters may be pre-configured to the terminal device in other pre-agreed manners.

Optionally, in the embodiment of the present application, the configuration message is carried in a system broadcast message or a dedicated message.

Optionally, in the embodiment of the present application, the terminal device determines that the first time domain sending location is that the first data of the first service conflicts with the data of the second service; the terminal device may determine the adjustment offset, and based on the Adjusting the offset, adjusting the first scheduling period to obtain a second scheduling period; according to the second scheduling period, the terminal device determines the second time domain sending location; and in the second time domain sending location, sending the first data. At this time, the data sending end of the terminal device may be a terminal device or a network device.

For example, as shown in FIG. 3, service 1 and service 2 of a certain terminal device perform data transmission according to a corresponding scheduling period (service 1 is a scheduling period T1 and service 2 is a scheduling period T2). A resource conflict occurs between data 5 of service 1 and data 3 of service 2. For example, as shown in FIG. 3, the terminal device may adjust the scheduling period T1 of the service 1, and the terminal device may first determine the adjustment offset 1 and adjust the scheduling period T1 to the scheduling period T3 according to the adjustment offset 1. The data 5 of the service 1 is transmitted in accordance with the scheduling period T3.

Optionally, in the embodiment of the present application, the terminal device may determine the adjustment offset of the scheduling period of each service according to the priority order of the services in which the resources conflict occurs, that is, the back-off sequence of the service transmission data. The value of the priority order and the adjustment offset of each service may be configured by the network device to the terminal device.

For example, as shown in FIG. 3, the priority of the service 1 is lower than the priority of the service 2, and the service 2 can perform data transmission according to the original scheduling period, and for the service 1, the time corresponding to the scheduling offset 1 can be backed off.

Optionally, in the embodiment of the present application, the network device may directly allocate the adjustment offset corresponding to each service to the terminal device directly, and when the service resource conflict occurs, the terminal device adjusts the offset according to the configuration of the network device. The scheduling period of the service is adjusted.

The resource conflict and resource collision mentioned in the embodiment of the present application means that the data is transmitted using the same resource, and the receiving end cannot obtain the data packet sent by using the same resource. The resource may be a time-frequency resource, or a time-frequency code domain resource, or a time-frequency code space domain resource, and specifically refers to a dimension of a resource that sends a data packet.

Optionally, in the embodiment of the present application, after the first data of the first service is sent according to the second scheduling period, the third scheduling period may be determined, and the first service is sent according to the third scheduling period. And a second data, where the difference between the first scheduling period and the third scheduling period is equal to a difference between the second scheduling period and the first scheduling period, where the second data is data sent after the first data .

For example, as shown in FIG. 4, after the data 5 of the service 1 is sent according to the scheduling period T3, the period T4 may be scheduled, where the difference between the scheduling period T1 and the scheduling period T3 may be equal to the scheduling period T4 and the scheduling period T1. The difference is sent to the data 1 of the service 1 according to the adjusted scheduling period.

Optionally, in the embodiment of the present application, after the second data of the first service is sent, the third data of the first service is sent according to the first scheduling period, where the third data is the second Data sent after the data.

For example, as shown in FIG. 4, after the data 6 of the service 1 is transmitted according to the scheduling period T4, the data after the data 6 may be transmitted in accordance with the scheduling period T1, for example, data 7, data 8, data 9, and the like.

Optionally, the terminal device may determine the adjustment offset within a range of values of the configured adjustment offset. The terminal devices can be configured with the same value range, and each terminal device can randomly select the adjustment offset within the value range. In this case, the network device may send an activation message to the terminal device, and the activation message is used to activate the terminal device to adjust the current scheduling period. Then, the terminal device may select the adjustment offset from the configured value range. At this time, the data receiving end of the terminal device may be a network device or another terminal device.

Alternatively, the network device may also only configure an adjustment offset having a value, and the network device adjusts the scheduling period according to the value. Specifically, the scheduling period may be adjusted after receiving the activation message sent by the network device.

For example, in the case of no system coverage or the system cannot indicate corresponding resources through control signaling, a persistent resource conflict may occur in the same service period of each terminal, for example, as shown in FIG. 5, the terminal device 1 and the terminal device 2 The scheduling cycle continues to collide. Then, the terminal device can randomly adjust the offset amount from the range of the adjustment offset to adjust the current scheduling period, instead of merely performing the transmission of the service according to the preset initial scheduling period.

Optionally, in the embodiment of the present application, the terminal device may send indication information, where the indication information is used to indicate a value of the adjustment offset selected by the terminal device. The indication information can be sent in the following manner:

The indication information is carried in a physical layer control channel, for example, the indication information may be physical layer control information, such as a scheduling indication (SA) in an LTE D2D transmission; or

The indication information is carried in a reserved bit of the physical layer channel, for example, after the transmitted data or control signaling, n-bit information is reserved, indicating the value of the possible 2n adjustment offsets; or

The indication information is carried in a specific MAC Control Unit (CE); or

The indication information is carried in a system broadcast message.
